at least
1. No less than (a certain amount). I didn't expect so many guests! We'll need at least five more seats at the table for dinner. I try to keep at least $1,000 in my bank account at all times.
2. Used to emphasize a positive occurrence amid disappointments. At least it only rained for two days of your trip! OK so Tom didn't come over tonight. At least he still called you.
at least so many
no less than; no fewer than. There were at least four people there that I knew. I want to spend at least three weeks in Mexico.
